To respond to Brian's question about AWIPS-II...While it's true that AWIPS-II stores its data in HDF-5, the metadata is stored in a Postgres database. So, while you may have the data itself in an HDF5 store, you won't know anything about it without the database. I'm not completely sure why the system was designed that way, but there you have it.

This seems like as good a time as any to chime in ... I have always been frustrated w/ the fact that Unidata NetCDF is not the same as AWIPS NetCDF. I thought the whole reason to have NetCDF files is that they are a Common Data Format (CDF). What's even more puzzling is that the folks who develop AWIPS (GSD) work right down the road from Unidata. You would think there would be more collaboration? OK, enough soap boxing ... hopefully my comments haven't turned you away and you are still reading ... what I'm mainly interested in is the future. I'd like to make sure that the problems of the past do not repeat themselves. So, with that said, are the IDV developers working closely (or at all?) with the AWIPS II developers? Will IDV be able to display AWIPS II data (which is mainly in HDF vs. NetCDF from what I understand)? Thanks for listening! Sorry if I've offended anyone.

From your analysis, it looks like the IDV (actually the netCDF-Java library) might not be doing this correctly. It could be that the format of the AWIPS grids has changed slightly since the convention was written many years ago, or the file is not written correctly.Don Murray Matt Foster wrote:I'm trying to view an AWIPS NetCDF model grid file, and I'm getting an error when trying to load it. The error is coming from line 186 of AWIPSConvention.java, which is the breakupLevels() method. The error is a "NoSuchElementException" coming from the StringTokenizer.nextToken().I'm guessing someone is probably going to want to see the grid file in question. gzip'd it is around 700MB, so I'm not sure how to go about getting it available to others.Any suggestions would be greatly appreciated. This is data relating to the tornado outbreak we had here on Monday, so there is great interest in viewing it outside of AWIPS.Matt @ WFO OUN ------------------------------------------------------------------------ _______________________________________________ idvusers mailing list idvusers@xxxxxxxxxxxxxxxxFor list information, to unsubscribe, visit: http://www.unidata.ucar.edu/mailing_lists/
